ASH-CONVEYER.

To all 'whom z't may concern.'

Be it known that I, TowNnn K. WEBSTER, Jr., a citizen of the United States, residing at Evanston, in the county of CookV and State of Illinois, have invented a certain new andiuseful Improvement in Ash-Conveyers,

of which'the following is a full, clear, concise, and`exact description, reference being had to the'accompanying drawings, forming a part of this speciication.

My invention relates to. ash conveyers of the type wherein steam or other fluid under compression is passed through a conduit for conducting ashes through the same conduit i retains a considerable quantity of very tine -in whichl F igure 1 is an elevational view of a boiler ashes or as h dust which passes through the vent opening with the remaining steam. The pollution of the atmosphere in this Inanner is, of course, objectionable and particularly so in congested districts. This objection can be partially overcome byinstalling a long vent pipe leading from the ash hopperto the top of a high building. Such an installation is, however, quite an expense and furthermore is unsightly vin appearance.

It isthe object of my invention to provide if efficient :and economical means for actingy uponthe escaping steam and ash dustand ultimately depositing the' dust in vconcrete form in a separate and distinct tank which is easilyv accessible and which'can becleaned without the necessity of'enteringthe chamber from which the ash dust -i's expelled to the tank. invention will be more fully pointedout in connection with the accompanying drawings room and ash vconveyer whichisyprovided with the system of our invention, some 5o the parts being illustrated in section to more clearly show their construction; and l Fig, 2 .is a fragmentary detailed vertical cross-sectional view of the chamber herein- Speeication of Letters Patent.

These andother objects of my Patented J an. S, i918.

Application led August 2.8, 1916. Serial No. 11!.'?,20 'Y ,l Y l -is a conduit 5 and provided at one end with an upwardly turning elbow 6 communicating with the conduit 7. The'upper end of the conduit 7 empties into an ash hopper or receptacle 8 preferably held, as shown, upon a support 9 above the ground. The lower end of the hopper carries a trap door 10 which when opened permits the removal of ashes from the hopper. 4into a vehicle or other container positioned under the hopper.

The conduit 5 is provided with a plurality of intake Ts 11-11 positioned in front of the several furnaces. Each intake T is provided with a plate normally closing the opening of the upwardly extending arm of the T. Extending upwardly within the elbow 6 is a steamlinjectorllZ connected by a pipe 13 with any suitable steam supply such, for example, as the boiler 3. A.- valve 14 is provided in the pipe 13 which when opened permits the passage of steam through the injector 12 and upwardly through the conduit 7 into the hop-per. As the steam is thus projected upwardly across'` the horizontally lying conduit 5 a vacuum-or reduction of pressure is created -in the conduit 5 so that upon removing one of thel cover plates pro vided in the Ts andthe insertion of ashes in ,such intake T .the'ashes will be conducted Y upwardly into the receptacle or `hopper 8.

During this transportation of the ashes from the boiler 'rpomto-.the hopper a small portion ofthe weight rof steam.employed is condensedl in" "ashes while the remainder isfpermitted,tqgiescape through a vent pipe illustrated at15.-This escaping steam'has adherlng to it .ai `cor'isidq-:rable quantity"`f very `fine ashes 'or/ash dust which is finally deposited in a second tank by the means Il will new, describe. The vent pipe 15 preferably extends downf.f.fwardly-from the hopper and has attachedl -theretov a'pipe 16 forming a condensing or mixing chamber. The lower end of this pipe communicates with a. T 17 through the horizontal arm 'of which a water supply.

pipe 18 extends. Positioned under the lower arm of the T 17 is the ash dust tank 20 provided at its upper end with an overliow pipe 21 the purpose of which will be presently described.

The water supply vpipe 18, as most clearly illustrated in Fig. 2, communicates with a. nozzle pipe 22 extending longitudinally within the condensing pipe 16 and is provided along its length with a plurality of small outlet openings 23 arranged to project `cold water infine streams into the condensing or mixing pipe 16.

The operation of the devices is as follows: As the steam and ash dust enters the mixing orcondensing chamber 16 the steam is condensed and the ash dust intermingled with the water supplied through the nozzle 22. As the water flows out through the lower arm of T 17 it carries with it the condensed steam andthe ash dust which adhered to the steam before the condensation took place and flows into the concreting tank 20. The concreting tank 20 is con structed of such size and shape. that very little agitation is produced in the tank during the flow of water from the condensing chamber to the tank so that the ash dustis permitted to gradually sink to the bottom thereof in concrete form. On accountof the overflow pipe 2l the clear water is allowed to flow away and leave behind it the dust. lVhen a suflicient quantity of dust has' co1- lected in the tank it can be easily removed without entering the condensing or mixing chamber 16, as is apparent from Fig. 1 ofthe drawings.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is:

1. An ash conveyer comprising an ash receptacle, a conduit having one end thereof communicating with the ash receptacle and its other end adapted to receive ashes to be transmitted to the receptacle, a steam nozzle in the conduit intermediate the ends thereof and arranged to direct steam through the conduit into the receptacle, whereby the ashes are conducted by the steam to the ash receptacle, a steam condensing chamber communicating with the upper part of the ash receptacle, a nozzle in said chamber arranged to project water against the' steam and ash dust entering the condensing chamber from the ash receptacle to condense the steam and intermingle with the ash dust, and an ash dust concreting tank separate from the condensing chamber and arranged to receive from the chamber, in one mass,

the water supplied through the nozzle, the' condensed steam and the ash dust', said tank being arranged to permit overflow of water at its upper portion, whereby the ash dust settles in the bottom of the tank in a conceptacle, a conduit having one end thereof e communicating with the ash receptacle and its other end adapted to receive ashes to be transmitted to the receptacle, a nozzle in the conduit intermediate the ends thereof and arranged to direct a. fluid through the conduit into the receptacle, whereby the ashes are conducted by the luid'to the ash receptacle, a mixing chamber communicating with the upper part of the ash receptacle, means in said chamber arranged to project water against the ash .dust entering the mixing chamber from the ash receptacler to intermingle the ash dust with the water, and an ash dust tank separate from the mixing chamber arranged to receive from the cham# ber the water supplied through the said means,'and the ash dust, said tank being arranged to permit overflow of water at its upper portion, whereby the ash dust settles in the bottom of the tank and the clear Water passes off at the top thereof.

4, An ash conveyer comprising an ash receptacle, a conduit having one end thereof communicating with the ash receptacle and its other end adapted to receive ashes to be conducted to the receptacle, a steam nozzle arranged to direct steam through the conduit into the receptacle. whereby the ashes are conducted by the steam to the ash receptacle, a steam condensing chamber communicating with the upper part of the ash recep message from the chamber, in one mass, the water supplied through the nozzle, the condensed.
